SPECIFICATION forming part of Letters Patent No. 410,402, dated September 3, 1889.

Application filed April 13, 1888- Serial No. 270,511. (No model.)

To all whom it may cnoern:

Be it known that we, HENRY COOPER, of Brooklyn, in the county of Kings and State of New York, and JAMES P. OBRIEN, of the city, county, and State of New York, have i11- vented a new and useful Improvement in Coin-Controlled Blow-Testing Machines, of which the following is a specification.

This invention relates to machinery for re- 1 o ceivin g and automatically indicating the force of a blow, particularly those which are set for action by and can be operated only on insertion of a coin of certain size or weight. These machines generally comprise a mova- 15 ble padded punching-head on which the blow is struck, a spring or other reacting device acting on the punching-head against the force of the blow, an index adapted to be operated by the punching-head and to indicate the extent of movement of the same and thus the force of the blow, means for temporarily retaining the index at the point to which it is moved, so that it can be observed by the striker and for afterward returning the index to zero and a contrivance whereby the machine is rendered operative on and only on insertion of the proper coin.

The objects of the present invention are to absolutely prevent the movement of the 0 punching-head except when released by the payment of the proper coin; to inform the intending user when and whether the punching-head is locked or released; to secure the immediate return of the punching-head to its 3 5 normal position and the automatic locking of the same after each blow is struck, while at the same time providing for the temporary locking of the index at the point to which it is moved and preventing it from being thrown 40 beyond that point by its momentum, and to provide for the release of the index and its return to zero a short time afterward, either automatically or by hand, all by simple and efficient means.

The invention consists in various novel combinations of parts and features of construction and arrangement; and in order that the invention may be fully understood we will first describe in detail the mode in which the invention may be carried into effect, and then point out its various novel featuresin the claims.

Reference is to be had by letters to the ac companying drawings, forminga part of this specification, in which- Figure 1 is a vertical section of a coin-controlled blow-testing machine embodying our invention on the line 1 1, Fig. 2. Fig. 2 is a vertical section of the said machine on the line 2 2, Fig. 1. Fig. 3 is a face view of the same. Fig. 4 is a sectional plan view of the same on the line 4 4, Fig. 1. Fig. 5 is a sectional plan View of the same on the line 5 5, Fig. 1. Fig. 6 is a sectional plan of the same on the line 6 0, Fig. 1. Fig.7 is a detail view of parts of the same, hereinafter referred to.

In the invention thus illustrated an upright case A is mounted on a base appropriate thereto, and the standard A, forming the front of the case, is provided on its face with a circu- 7o lar scale B, the graduations of which are numbered in order to denote pounds. A padded head 0, having a tubular shank O, is arranged to project from the front of the case A at a convenient height for the average man to punch or strike, and the shank O is mounted to slide lengthwise in a fixed tubular guide 0 projecting from the back of the standard A and having a rear head 0 between which and the punching-head O is interposed a stiE 8o coiled spring O", by which the punching-head O is normally held projected, but which will permit the head C to be forced inward when struck a distance corresponding to the force of the blow. The shank O is provided with a projecting lug D, which rides in a longitudinal slot formed in the guide 0 so as to prevent the shank from turning and to limit its movement in the guide, and the lug D is utilized for the attachment of a cable D, which is carried forward around a stationary pulley D then upward, and attached to the lower end of a bar E, which is mounted to slide vertically in guides E on the back of the standard A. A spring E is arranged by its reaction to force the bar E normally upward, a stop E being provided to limit the movement of the bar E, and the bar E is provided with a rack E, with which is geared a pinion E fixed on an arbor, which projects through the standard A at the center of the scale B, on the face thereof, and carries an index E which is adapted to turn over and register with the divisions of the scale B. The arrangement is such that the index E will normally point to zero of the scale; but when the punching-head is struck will, through the action of the sliding shank C on the cable D and the sliding bar E, turn the pinion E and thus the index, until the latter registers with a number of the scale equal to the number of pounds representing the force of the blow. The bar E is provided with a series of ratchet-teeth F, with which a catch F is held engaged by gravity or a spring, so that when the bar E is thrown downward, as above described, it will be automatically locked by the catch F in its lower position, and the index E thu-s retained at the division to which it was turned.

The catch F is provided with a shoulder F in connection with which is arranged the pivotal lever G in such a manner that when the lever is swung on its pivot it will strike the shoulder F and disengage the catch F from the ratchet-teeth F. The lever G is arranged in the path of a weighted tripper Gr, suspended from a cable G which winds on a drum G pivoted to the back of the standard A. Another cable is wound reversely on the drum and sustains a weight Gr lighter than the Weighted tripper G, and to the drum G is attached a fiy-wheel H, having a pin H, which is arranged in the path of a pivotal striker H pivoted to the standard A and having a sliding connection with the sliding bar E by forking the inner end of said striker and passing it between upper and lower pins S S respectively, on the bar E, the arrangement being such that owing to the excessive gravity of the weighted tripper G it will normally overbalance the weight G and rest on the tripping-lever G, so as to keep the catch F out of engagement with the bar E; but when the bar E is forced downward, as described, the short arm of the striker H connected therewith will be thrown upward to strike the pin H on the fiy-wheel lI, spin the same in the direction indicated by the arrow at, and thus raise the weighted tripper G. The tripping-lever G will be thus temporarily relieved of the weight of the tripper G and will allow the catch F to dog and lock the bar E, as before stated, until, the momentum of the flywheel H being exhausted, the weighted tripper G again falls, (the fly-wheel acting as a speedcheck,) strikes the tripping-lever G,and disengages the catch F, so as to permit the bar E to be returned by its actuating-spring E to its normal upward position. The c I tch F is also provided with a cam I, in posi ion to be engaged by one end of the weighted lever I, which is pivoted to the standard A and carries on its other end a loose pulley 1 the arrangement being such that when the lever I is swung contra-clockwise on its pivot it also will cause the catch F to be disengaged from the bar E. Over the loose pulley I is suspended a cord 1 one end of which sustains a weight 1 and the other end a coin-receptacle l of slightly less weight than the weight I, and from the front of the standard leads a chute J, of a size adapted only to coin of the denomination or character which it is proposed to use, so as to deposit the coin in the receptacle 1 so that while the weight of the opposite arm of the lever I will normally counterbalance that of the cord 1 the weight 1 and the receptacle 1 so as to keep the lever I from acting on the cam I of the catch F,when the coin drops into the receptacle I the additional weight of the coin will cause the lever I to swing and disengage the catch F, and at the same time cause the receptacle 1 to overbalance the weight I and fall, so as to lift the said weight. The receptacle 1 is provided with a movable bottom I, having an arm I which is adapted to strike a projection K, fixed to the standard A, when the receptacle I reaches the lower end of its movement, and dump the bottom I, permitting the coin to fall out, the receptacle 1 to be again elevated by the weight 1 and the lever I to return to its normal position and leave the catch F free to engage the bar E. A chute L is arranged to receive the coin falling from the receptacle I and convey it to a second receptacle M, carried by one end of the lever M, which is pivoted to the standard A, and

has a weight M on its other end, which will normally overbalance the receptacle M, but when the coin is deposited therein will be overbalanced thereby and swung upward. The weighted end M of the lever M forms a bolt, which is adapted normallythat is, when the punching-head is projectedto enter between the shoulders of corresponding cross-slots N, formed in the sides of the tubular shank O of the punching-head C, and also in its tubular guide 6 so as to lock the punching-head against movement; but when the lever M is swung upward, as before described, the bolt will be withdrawn from the cross-slots N, and the punching-head will be thus set free for action. The sliding shank O is provided with a tripper O, as best shown in Fig. 6, which is arranged to strike, when the shank O is forced inward, the arm of a lever 0 which is connected by a cord 0 with the dumping bottom 0 with which the coinreceptacle M is provided, open the said bottom and permit the coin to fall into a final receptacle 0 provided therefor, so that when the shank C is again projected by its reacting spring C the weight of the bolt M will tend to cause the bolt to return and lock the shank O to its guide, as before described.

In the front of the standard A is provided a window P, back of which is pivoted to swing a carrier P, supporting a double sign P on one part of which may be printed or produced the words Wait for signal, or a warning of similar import, and on the other part the word Time, or a signal of like meaning; and the carrier P is connected by a rod or line P with the locking-lever M, the arrangement being such that when the punchinghead 0 is locked by means of the bolt the above warning-\Vait for signalwill appear at the window P, but when the lever M is swung to release the punching-head, as before described, the sign I? will be moved and the above-stated signalTime-be revealed at the window, indicating that the punchinghead is ready for action.

In order that the number of times the punching-head is struck may be automatically registered, we arrange a register-R and registeroperating lever r of common form within the case A, and pass an arm of the lever r between pins r on the vertically-reciprocating bar E, so that the register will be operated by each reciprocation of the bar E.

To review the operation briefly: The punching-head will be normally locked and the catch F disengaged from the bar E, but when the coin is dropped into the admission-chute J the punching-head will be released and the signal to strike displayed. NVhen the punching-head is struck, the catch F will be for a shorttime allowed to engage the bar E and will retain the same, together with the index, in the position into which they are thrown, while the locking-lever M will be left free to engage the punching-head shank C. When the weighted tripper G, returning, again disengages the catch F, the bar E will be returned to its normal position, the punchinghead having been previously retracted by its spring immediately after being struck and automatically locked by the lever B so that the machine is automatically reset for operation by the succeeding coin when it may be deposited.

In some instances the case A may be designed in the form of a man with a punching-head 0 arranged at or near his stomach and the recording-scale on his chest.
